ATTORNEYS Uited States Patent DOMED T91 DISPENSING CAN John Henchert,River Forest, Ill., assignor to Continental Can Company, Inc, New York,N. Y., a corporation at New York Implication December 16, 1954, SerialNo. 475,725

1 Claim. ((31. 222-443) The invention relates to new and usefulimprovements in a container for dispensing fluid under pressure and moreparticularly to a protective cap for covering the dispensing unit forpreventing accidental operation of the same.

An object of the invention is to provide a protective cap for adispensing container which not only prevents accidental operation of adispensing unit but which cap is so constructed as to aid in stackingone container on another.

A further object of the invention is to provide a dispensing containerhaving an inwardly dome shaped bottom end and an annular groove disposedconcentric to the center of said bottom end with a protective capfrictionally held on the container, which cap has a peripheral ribdimensioned so as to fit in the groove in the bottom end of a containerstacked thereon.

In the drawings which shOW by way of illustration one embodiment of theinvention:

Figure 1 is a view partly in section and partly in side elevation of adispensing container embodying the improvements and showing onecontainer stacked on another,

Figure 2 is an enlarged sectional view of the protective cap for thedispensing container.

Figure 3 is a view of the bottom end of the dispensing container.

The dispensing container to which the invention is applied is of theordinary construction and includes a body 1 to which an inwardly domeshaped bottom end 2 is secured by a double seam 3. This bottom end ofthe container is provided with an annular groove 4 which is concentricto the center of the bottom end of the container. The groove ispreferably disposed midway between the center and the seam 3 joining thebottom end to the container. At the upper end of the container is anoutwardly dome-shaped top end 5 which is secured to the body 1 by theusual double seam indicated at 6. Disposed at the upper end of thisdome-shaped top end is a dispensing unit 7 of any well knownconstruction. The dispensing of the liquid which is retained in thecontainer under pressure is controlled by a fingerpiece 8. also of theusual construction. When the fingerpiece is depressed or moved endwiseit causes a valve to be opened so that the fluid in the container isdispensed through an opening 9 in the fingerpiece. The dispensingcontainer referred to is commonly used for dispensing aerosol liquidsunder pressure. The essential feature of this type of container is themanually actuated fingerpiece which opens a passage for the dispensingof the fluid contained in the conice tainer. When the finger-piece isreleased it is common to provide means whereby the fingerpiece will bereturned to its initial position so as to cut off further dispensing ofthe liquid.

In order to prevent accidental operation of the fingerpiece applicanthas provided a protective cap 10 which has a top end 11 and a dependingskirt 12 rolled into a closed head 13 at the lower edge thereof. Thedomeshaped top end of the dispensing container is shaped so as toprovide a substantially vertical friction wall 14. The depending skirtis so dimensioned relative to this friction wall that when the cap isplaced on the dome-shaped top end of the container it will engage thisfriction wall and be held firmly in place on the dispensing container.The top end of the cap when attached to the dispensing container isspaced away from the fingerpiece 3 so that any accidental contact withthe cap will not in any way be transmitted to the fingerpiece. As longas the cap is permanently secured to the container there is no possiblechance of the fingerpiece being accidentally depressed so as to open thedispensing passage.

The protective cap is provided with a peripheral rib 15 which isdimensioned and positioned so that when another container is stacked onthe cap said rib 15 will fit snugly in the groove 4. This will supportthe containers when stacked one on another.

The cap when attached to the container will be firmly held in place bythe beaded lower end of the skirt engaging the friction seat upon thedome-shaped top end. This cap performs the double function of protectingthe fingerpiece of the dispensing device from being accidentally openedand it will also provide a means whereby one container can be stacked onanother and firmly held in the stacked relation.

It is obvious that minor changes in the details of construction may bemade without departing from the spirit of invention as set forth in theappended claim.

I claim:

A dispensing container comprising a body portion having an inwardlydome-shaped bottom end, said end being provided with a downwardlyopening continuous circular groove concentric to the center of saidbottom, an outwardly dome-shaped top end terminating in a manuallycontrollable dispensing device, said top end having an upstandingfriction seat disposed below and outwardly from said manuallycontrollable dispensing device and a stacking and dispensing deviceshielding cap having 21 depending skirt dimensioned so as tofrictionally engage said seat and project upwardly about the dispensingdevice on said top end, said cap having a raised continuous circular ribat the periphery of its upper end extremity, said rib being dimensionedand positioned so as to be engageable in the groove in the bottom end ofa container stacked thereon, said upper end extremity of said cap beingdisposed above and out of contact with said dispensing device.
